Diplomatic tensions and the "aggressive policy" of the U.S. toward Moscow are of more concern than economic sanctions, the president and chairman of Russia's VTB Bank Andrei Kostin said.
"What concerns me more than any economic sanctions, that for the first time since the Cuban (missile) crisis — people, at least in Russia and probably in America also, have started to feel that there is more danger of World War III," Kostin told CNBC's Geoff Cutmore in Moscow.
"There is a recent public opinion poll (in) Russia (that) showed that 55% of Russians now believe or think that World War III is possible because of the aggressive policy of the United States," he added.
"It's very, very serious to reflect on what's happening in national affairs. The world is becoming a much more dangerous place to live," he said. "And that's a great concern."
